fragment_sign_up.xml：`

android:layout_marginTop="30dp"
android:layout_weight="1">
<com.twitter.sdk.android.core.identity.TwitterLoginButton
android:id="@+id/twitter1"
android:layout_width="40dp"
android:layout_height="40dp"
android:visibility="gone"/>
<ImageButton
android:id="@+id/twitter_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/twitter_icon" />
</FrameLayout>`
点击按钮后，它会重定向到Twitter登录页面，点击“连接”按钮后，它只返回到片段，不显示Toast消息。当我第二次单击该按钮时，它会显示来自故障方法的烤面包。
